<SampleDescription>
 <p>This sample demonstrates the Blazor DataGrid header template feature. In this sample, we have shown custom icons in the column headers.</p>   
</SampleDescription>
<ActionDescription>
   <p>The Header Template has options to display custom element value or content in the header area. You can use the <code><a target='_blank' class='code' href='https://help.syncfusion.com/cr/aspnetcore-blazor/Syncfusion.Blazor~Syncfusion.Blazor.Grids.GridColumn~HeaderTemplate.html'>HeaderTemplate</a></code> of the <code><a target='_blank' class='code' href='https://help.syncfusion.com/cr/aspnetcore-blazor/Syncfusion.Blazor~Syncfusion.Blazor.Grids.GridColumn.html'>GridColumn</a></code> component to specify the custom content to be displayed in the header section.</p>
   <p>In this demo, we have presented Employee Information with image using the header template.</p>
   <p>More information on the header template can be found in this <a target='_blank' href='https://blazor.syncfusion.com/documentation/grid/columns/#header-template'>documentation section</a>.</p>
